Ruko Terrax Spiral Drill HSS-CO5 2.5 mm in a 1 Plastic

• Ground drill bit set in high performance high speed steel with increased cobalt content.
• The cobalt content ensures high temperature resistance.
• The completely ground bits have an increased drilling precision.
• High performance drill bits for all normal drilling jobs in all common materials.

Twist drill DIN 338 type N HSS-G Co 5 Powerful twist drill, suitable for all normal drilling work in common materials. Ground twist drill made of high-performance high speed steel with increased cobalt content. The fully ground twist drill has increased concentricity. The cobalt content ensures higher heat hardness resistance. Areas of application: for unalloyed and alloyed steels (strength of up to 1100 N/mm²), hot and cold working steels, tempering and application steels as well as for rust and acid-resistant steels. Specifications: Diameter: 2.5 mm Total length: 57.0 mm Spiral length: 30.0 mm Tip finish: tapered jacket finish: normal grinding * point angle: 130° spiral angle: 20-30° Ø tolerance: h8 surface: golden brown right-hand cutting packaging unit: 1 piece in plastic packagingNormal grinding Application: R&D all common drilling work in steel, non-ferrous metals and plastics.The tip angles depend on the machinability of the materials. Advantages: powerful main blades, resistant to impact and side forths.Easy hand sharpening possible. Disadvantages: Wide cross blade requires high feed force.
